Steelfists said:
The Allies demanded Japan's unconditional surrender. They refused.
And once again, to quote the report:
"Japan would have surrendered even if atom bombs had not been dropped, even if Russia had not entered the war, and even if no invasion had been planned or contemplated.
The Hiroshima and Nagasaki bombs did not defeat Japan, nor by the testimony of the leaders who ended the war did they persuade Japan to accept unconditional surrender."
Ok, now here's the thing. Japan didn't want unconditional surrender. They wanted to retain the figurehead of their Emperor. That was all. It was described by the governments own reports as "a formality" in Japanese surrender requests going back for two years before the bombings. ~TWO YEARS~ Regardless, we could have pushed for it or not, but the fact of the matter is we didn't need to do anything to achieve "unconditional surrender."
The bombings were unnecessary on any grounds. Any grounds at all. Even to prevent invasion.
